Patented May 28,1912.

To all whom u may concern:

. Be it known that I REYNOLDS C. .FRAMP- TON, a citizenof t-he United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements 1n' Burners, of which the followingls a SPQClfi-i cation; y

Thejinventionrelates to burners of the general type shown in the patent to Buerklei No. 637 ,850 issued Nov. 28, 1899, and used -primarily on. instantaneoumwater heaters,

andhas for its principal ob'iects; the proo vision of'a burner in-which 'all danger-of back firing is eliminated; the provision of a burner inwhich better combustion is'securedthan in. the-burners of the same general type a as heretofore;constructed; the provision of a';burner capable of eflicient service under zo'rwldelywarying conditionsof pressure, andwith var-yin qualities of gas; the provision of a burner aving improved means for disosin'g of any' condensation from the coils neath which the burners are commonly 'employed;- and the provision of a burner construction wherein the flame is thrown clear of'the burner casting and overheating of the castin and gauze in contact therewithsis avoi ed. One embodiment of the ,30-inventionisillustrated in the accompanying drawings, wherein Figure 1 is a side view of the burner,

Flgure 2 isia similar view with the s de F'gure 3 is an end view of the burner,

Figure 41s a transverse section of the burner on the line IV-IV of Figure 1,

'gigure 5 is a side view of the cap plate,- "Ltjl-Il I wi g-tFigure 6 is a face view-of one of theside p tes- Referring to the drawi n 1 is the body porteonfof the burner, inw ich the gas and "eir-;""are' mixed, and which is designed to be screw bolt Gland -7 are side plates which are clamped in position by means ofthe transverse screw bolts 88.

The cap plate 5 is provided on each side with a series of passages or troughs 9,whi ch I cap passages extend from the lower edge of the y reference to Fig; 6 it will be seen that the uppei'inner edge of the side plate 7 is plain, and this upperedge surface fits against and covers the lower portions of the passaes 9 in thecap plate, the extreme upper e go of the side plate fitting against a' shoulder 10 (Figs, 4: and.5) formed upon the cap plate. The-passage's'S) are pre ably-somewhat tapered as will be seen by reference to Figures 4: and 5, the cross sectional area of such passages decreasing from the lower or inner ends of the passagestd their upper or outer ends. The cap' late. 5is preferably made 'approximately V s ape a igure 4,.

in cross section as indicated in and is provided at one end with a spout 11S 1 by "means of 'ivhich the condensation s01 lecting in thecap may bejdrain'ed away.

"The cap plate intermediate. the spouts or passages 9 is notched as indicated at 12, andgrooves 13 extending downward from thelower ends of such notches are ro provided with grooves 14 which form con- 'vided .in the side faces of thecap p ate. The upper edges of the side plates 7 aresalso.

tinuations of the grooves 13. The cap plate 5 is preferably made to fit down upon-the body portion 1 somewhat looselyv atthe point 15 (Fig. 3), sothat 'a slight amount of gas escapes at this point, and by its combustion serves to communicate the flame to the next burner, which arrangement is desirable as the burners. are ordinarily 'arranged in series upon a,circular supporting pipe, and'after one of the burners has been lighted the other burners must be sucees sively lighted from each other.

A number of objects are attainedpy reason of the structure as heretofore described.

The provision of theelongated, narrow spouts 9 in the cap-plateelimmates the possibility of the flame working back to the space between the face plate 7 and perfomental as it is injurious to the perforated 'rated plate 4, which back firing is detriplate, and spot is formed by "combustion at this point. Furthermore the spouts by reason of their arrangement and contour tend 9. The

to cause the ignited gas to burn out and awayfrom-the upper-edge of the burner, thus avoidingthe danger of overheating the metal The provision-of the notches 12 and the grooves 13 I and 14, not only serves to keep the-cap plate cooler, but'als'o' permits better access of the surrounding air to the jetsof burning gas issuing from the s cuts.

10 the drainage of the condensation which ordinarily forms above the burners, and dripsdown upon it. .It will also be seen thatthe passages, or spouts 9.are so widely separated that the jets of burning gas are an stantially independent, and therefore each jet has a better supply of air than would be the case ifthey formed a continuone sheet or were arranged close together. The arrangement whereby the burning fuel is projected-clear of the casting is advantageous furthermore, "in ,thatthe. burner is 1 more durable, due tothe fact that itis not overheated, "and burned out as is the case where the .flaine plays directly upon portions of the'bnrner in former constructions. The fact; that the burning fuel is projected; out and away from the burner permits the -i1se-of gasunder varying pre sures and of fvarying qualityws the comb, stion is much' 7 -130; .inore:cox'nplete than inthe burncrs as here tofore constructed, and/even Iwith gas/at --,lowpressure and of-;pb or quality ,there is -"no*possi bilityof.the flame creeping' back -"--.-'5through the lon 5'.i'gniting., the f!.18 I'adjacent; the perforated p ate.
